Hi there. I'm trying to figure out the best way to include a signature in a
struct. For example, if I have a struct like:
struct SignedTransaction {
transaction @0 :Transaction;
signature @1 :Signature;
}
I'd like to be able to sign the transaction bytes (i.e. the packed
Transaction on its own). Clearly I can just replace the transaction field
with the message bytes of building the Transaction separately, but I expect
packing would be less efficient, plus it creates a level of indirection to
access the transaction. Basically, I'd like to:
1. Build the transaction Struct separately
2. Pack it to bytes and get the signature
3. Create a SignedTransaction, using the already constructed Transaction.
4. When deserializing, I'd need to be able to pull out the packed
Transaction to verify the signature.
Is there any simple way to do this? Other ideas?
Thanks,
John
